Over 700 agencies provided over 160,000 treatment episodes for alcohol and other drug issues to an estimated 108,000 clients in Australia in 2012–13. Most episodes were for clients receiving treatment for their own drug use, and these clients tended to be male and in their 20s and 30s. Alcohol was the most common principal drug of concern, accounting for almost half of these closed episodes, and counselling was the most common type of treatment.
